                                <h3>题目描述</h3><p><div>L神犇在完虐各种弱菜后终日吃了睡，睡了吃，导致了体重直线飙升。一觉醒来的L神犇决定减肥。他将自己的食物分成n份，不满意度为0。</div>
<div>对与食物的不满意度定义如下：在修改最少x份食物的重量后可以令每份食物的重量均不同，x即为这种分配方案的不满意度，不满意度越小越有利减肥。</div>
<div>然而此时龙妹妹破门而入，让L神犇从每份食物中分出一定重量的食物给她。为了使龙妹妹也感到满意（难道龙妹妹也减肥？），L神犇决定将每份食物分成两份重量分别为ai,bi的食物（ai,bi均为非负整数，ai+bi=si）。L神犇和龙妹妹在一起，他们对于食物的满意度要求一致，a,b两组食物的不满意度均不大于n/3（向上取整）。</div>
<div>鉴于L神犇和龙妹妹在一起很忙，所以帮他们分配食物的任务就交给你了。</div>
<p></p></p><hr/><h3>输入格式</h3><p><div>第一行第一个正整数n。</div>
<div>第二行给出n个互不相等的整数s1，s2，s3...sn表示一份令L神犇满意的食物。</div>
<p></p></p><hr/><h3>输出格式</h3><p><div>如果存在可行的方案，使得食物可以按照他们的意愿分配，第一行输出&ldquo;YES&rdquo;。</div>
<div>第二行n个整数输出每份分给L神犇的食物重量。</div>
<div>第三行n个整数输出每份分给龙妹妹的食物重量。</div>
<div>如果不存在可行的分配方案，输出&ldquo;POOR LMM&rdquo;。</div>
<p></p></p><hr/><h3>样例输入</h3><pre>6
12 5 8 3 11 9</pre><hr/><h3>样例输出</h3><pre>YES
6 2 6 1 2 4
6 3 2 2 9 5</pre><hr/><h3>提示</h3><p><div>对于100%的数据n&lt;=5000，0&lt;=si&lt;=10^6</div>
<div>请不要提交，无SPJ</div>
<p></p></p><hr/><h3>题目来源</h3><p>没有写明来源</p>
